A walk around the office can reverse vascular dysfunction caused by hours at a computer

Across the country, many employees are seated at desks for the majority of an eight-hour workday. As technology creates an increase in sedentary lifestyles, the impact of sitting on vascular health is a rising concern. Now, researchers have found that when a person sits for six straight hours, vascular function is impaired -- but by walking for just 10 minutes after a prolonged period of sitting, vascular health can be restored.

It's easy for all of us to be consumed by work and lose track of time, subjecting ourselves to prolonged periods of inactivity," said Jaume Padilla, Ph.D., an assistant professor of nutrition and exercise physiology at the MU School of Medicine and lead author of the study. "However, our study found that when you sit for six straight hours, or the majority of an eight-hour work day, blood flow to your legs is greatly reduced. We also found that just 10 minutes of walking after sitting for an extended time reversed the detrimental consequences."
